We have developed the Siegling Extremultus power transmission belt range in close co-operation with users and OEMs. As a result, it can offer a market-driven range of types that can handle all sorts of power transmission in every industry.
Siegling Extremultus – exceptional power transmission
The properties The advantages
thin/flexible low power requirement, small pulley diameter
constant friction coefficient, constant RPM, long belf lifehigh wear-resistance
high elastic modulus short take-up ranges, low creep
laterally stiff good edge stability
good damping properties treats bearings gently, vibration-free operation

Product range
Helically-wound endless belts 10
Different materials for the friction and top coating are combined with one of the three tension member materials
– A (aramide)– E (polyester – also helically-wound
endless) or– P (polyamide)
Producing a varied range with ideal properties for each and every application.
Siegling Extremultus power transmission belts are extremely tough, elastic, absorb vibrations and shocks and can be used at belt velocities of up to 100 m/s.
Compared with other power transmission belts, they are easy to handle, extremely efficient and have a high level of synchro-nisation accuracy.
Apart from traditional pulleys, they can easily handle bevel and cone drives and drive several shafts, even in different rotational directions.

In addition to other advantages, flat belts are much more efficient than V-belts. In V-belts, energy losses occur, not just due to flexing in the material, but also due to friction at the sides and other aspects associated with the belt design.

Efficiency of a flat belt (top), efficiency of a V-belt (bottom). Siegling Extremultus flat belts have an efficiency of 98.6 %.
Friction on the sides at the top and bottom, internal friction losses due to hysteresis.

Urethane (U)The urethane friction layer U is mainly used for drives. Thanks to its low thickness, it is especially well-suited for extreme flexing stress.
Friction/top layer properties
Elastomer G (G)The friction coating elastomer G is used for all standard drives, also wherever dust and moisture are a factor. Not recommended when oil and grease are present (e.g. oil vapour).

no splice, as helically-wound endless
Power transmission belts with helically-wound endless tension members, made of polyester cord, require short take-up ranges, can transmit high specific levels of effective pull and are not sensitive to fluctuations in ambient conditions. Because they are very flexible and track very steadily and evenly, they are an excellent choice for high levels of power transmission (> 60 m/s) and multiple rotations.

* Minimum drum diameter was determined at room temperature. Lower temperatures require larger drum diameters. For the P line, this also applies in the case of low humidity.
Explanation of the abbreviations used, the type key and resistances on page 11.
** Nominal effective pull specifies the power transmission in N per mm belt width possible for the belt type (standard operating environ-ment).
*** Temperature can be briefly exceeded to a max. of + 20°C.
**** Depending on application, splice length given in brackets also possible.

Special properties/resistances (all lines)
Siegling Extremultus is antistatic.
Helically-wound endless types cannot be lengthened, shortened or repaired.
The Siegling Extremultus GT and GG types are not sensitive to oils and greases, as well as commonly-available solvents. However using in oily or greasy conditions (e.g. oil vapour) is not to be recommended (risk of the belt slipping – if possible use LT or LL types).
The Siegling Extremultus sub-types LL, LT and UU are impervious to machine oils, diesel fuels, petrol, benzene, commercially available solvents such as ethyl acetate, acetone, etc.; chlorinated hydrocarbons such as perchloroethylene, etc.
Siegling Extremultus is not resistant to organic and inorganic acids.
For further details, see the Siegling Extremultus – Technical information brochure (ref. no. 316).
